Remarks:

Calculate the difference for Vec elements [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1]. Size and Matrix::Complex properties of the calling Matrix must be set explicitly. The following formula is used to calculate the difference:

Δ[k]=Vec[k+1]Vec[k],0k<Vec.Length1\Delta [k] = \text{Vec}[k+1] - \text{Vec}[k], \quad 0\leq k < \text{Vec.Length}-1

An exception is raised if Matrix::ConditionCheck is True and array borders are overrun or underrun.
